UVStandardlichtquelle

UVStandardlichtquelle is a term that refers to a standardized light source emitting ultraviolet (UV) radiation. These sources are crucial for calibration, testing, and measurement in various scientific and industrial applications. Their primary characteristic is the stable and predictable emission spectrum within the UV range, which typically spans wavelengths from 10 nanometers to 400 nanometers.

Standardized UV light sources are often designed to replicate specific UV spectral distributions, such as those found in natural sunlight or produced by particular artificial sources. This allows for reproducible experimental conditions and reliable comparisons between different tests or instruments. They are commonly used in fields like materials science for testing UV resistance, in photochemistry for initiating reactions, and in metrology for calibrating UV detectors and spectrometers.

The construction of a UVStandardlichtquelle can vary, but common types include deuterium lamps, mercury vapor lamps, xenon arc lamps, and specialized LED arrays. Each type offers different spectral characteristics, intensity levels, and operational lifetimes. Calibration of these sources is a critical process, ensuring their output meets established standards and traceable to national or international metrology institutes. The stability and accuracy of the emitted UV radiation are paramount for the validity of results obtained using these light sources.
